Adam Teicher, of the Kansas City Star, reports Kansas City Chiefs FB Joe Hall appears to be an ideal candidate to be the eventual successor for Chiefs starting FB Tony Richardson, but Vermeil was disappointed in Hall when he returned for the start of the team's off-season conditioning program last week. "He's got all of the talent in the world, but he's about 330 pounds right now," Vermeil said. "I don't know if I've ever been around someone with that kind of athleticism at that size. He startles you. He catches the ball as well as anybody we have. But he's still immature. His only limitation is his own self-discipline, or lack of it. He will either mature or he won't be here."
